Indian culture has its roots in the Indus Valley Civilization, which flourished around 3300 BCE. The Vedic period, which followed, laid the foundation for Hinduism, one of the oldest surviving religions in the world. Over the centuries, India has been influenced by various invasions, migrations, and empires, including the Mughal, British, and Islamic dynasties. These external influences have significantly contributed to the country's cultural diversity, linguistic heritage, and architectural legacy.
